it depends on the kind of marimba. it ranges from 4 octaves to 5.5 octaves
A glockenspiel does not have a set number of keys. It can have twenty or thirty keys, depending on the size and number of octaves represented.
An 88-key piano has 7 octaves plus three additional keys - making the keyboard have 7 1/4 octaves in total. Some pianos also have exactly 7 octaves ranging from the A 3 octaves below middle C to the A three octaves higher than the A tuned to 440Hz (the A above middle C).
Every guitar can be played in any key. The keys will repeat as you go higher up on the neck. The amount of frets will dictate how many times certain keys can be repeated, but most keys can be played in two different octaves.
Xylophones vary in size, they can have anywhere from 4 to 5 octaves.

No. The piano does have eighty-eight keys, but including the black keys (sharps or flats), it takes twelve keys to make an entire octave, so it's closer to eight octaves.

There are 7 octaves on a standard grand piano (plus a minor third, or one additional "black key"). If each octave has 5 accidentals (or black keys) then 7 octaves would have 35 black keys, plus the additional B Flat at the bottom of the piano.....so: A 72 key piano has 36 black keys.
Most of modern pianos has 52 white and 36 black keys, which makes 7 and 1/4 octaves.
The answer is 7 octaves plus a minor third. (A0 to C8)Most grand pianos have 88 keys, which would give them a 7 octave plus m3rd range. However some older grand pianos have only 85 keys and even sometimes less, which would reduce the range of the piano.On a normal piano (one with 88 keys), you have 7 1/3 octaves. There are 12 (chromatic) notes per octave.
because notes come in octaves of 8 and 88 is a multiple of 8
60 = 12*5 5*7=35 white 5*5=25 black
In fact, the reason that the piano has 88 keys (or more than 7 octaves) is because that's the range that was finalized by the American Steinway piano makers in the early 20th Century. Until then, the piano's register had been growing constantly from the original 5 octaves (49 keys, F through F) of Mozart's pianos to 5.5 octaves (56 keys, F to high C) in Beethoven's required register, to 6 octaves (61 keys, F to high F) which were called for by Schubert, to 7 octaves (85 keys, A through high A), which is what most composers of the greatest piano music would have been content with. The Steinway manufacturers figured the highest note on the piano ought to be C rather than A, so they extended the range with three more keys in the upper register. It was there that the range of the modern piano would be finalized. Older pianos with 85 keys are still in existence though, especially in Europe. The Bösendorfer piano makers still make their "Imperial Grand" pianos with 100 keys, extending the range to over 8 octaves, from low C to D above that of the modern Steinway. Few composers have ever actually written for such a register, and as the extra notes are simply not popular enough to merit their being included in the standard piano, they remain only on the Bösendorfer Imperial Grand.
